Started from the bottom...... now we still at the bottom
C TIER
Goro: It's possible that Prince of Shokan may be greater than bottom 2 "C" tier material, but I do feel he is lacking enough to possibly be the second worst in the game. His lack of mobility is his biggest crutch. F+4 being made an overhead is huge; before he gained that, I feel he was worse than Kitana. Biggest strengths he has are fairly good pressure, as he has alot of 0 to +2 blockstrings, as well as above average combo damage in all three variants. It's hard to not pick Kuatan Warrior over the other variants because the ground pound is a huge tool in many matchups as a fullscreen check. The Kuatan b,f+2 "Corp Charge" is kinda redundant and booty as a footsie/armor tool as it is a high, but it an be used as a nice combo ender. Tigrar Fury might have potential in flamethrower blockstrings, and the low flame could be useful in matchups where he doesn't get zoned out heavily. Dragon Fangs is lacking but he does have that d/b+2 low which is like +6 on block which is unusual. The Dragon Fangs EX d,b+2 special also scales a bit less than EX punchwalk, 2,1,2 is a decent chip/spacing string, and his command grab does a bit more raw damage so this variation isn't entirely outclassed.
Kuatan Warrior = Tigrar Fury > Dragon Fangs
Kitana: Poor princess sorta feels like a stripped down version of MK9 Kitana which already would not work in this game engine. Her positive traits are that she has good meterless damage off of air fan and her BnB combo starters, and she is good at blowing up sloppy, impatient play. She is crippled by terrible frame data and a terrible 50/50 compared to the rest of the cast. Royal Storm lift is actually pretty good as a footsie tool. The reflect is disappointing as it doesn't activate fast enough to be used on reaction. Assassin's "niche" isn't as useful to use it over her other variants. The parry has slow startup and is weak. The fan sharpen is very difficult to activate safely. EX assassin dash, however, is fairly useful. Mournful trades in her meterless + metered damage in the other variants for aimable mid zoning and safe blockstrings with shadow kick. The glaives only deal 5% so there's really no reason to be that scared of them. It also hurts that the air glaive is abysmal.
Royal Storm > Mournful > Assassin
